Former NASA astronaut Scott Carpenter, the second American to orbit Earth, will talk about his new book, "For Spacious Skies: The Uncommon Journey of A Mercury Astronaut" on Tuesday, March 4, at 5:30 p.m. at the University of Colorado at Boulder. The talk is in the Old Main Chapel and is free and open to the public. Initially scheduled for January, the talk was rescheduled after a death in the Carpenter family. Kris Stoever, Carpenter's daughter, co-authored the book and will take part in the discussion.
